Flat feet (also called pes planus or fallen arches) is a postural deformity in which the arch of the foot collapses, with the entire sole of the foot coming into complete or near-complete contact with the ground. Some individuals (an estimated 20-30% of the general population) have an arch that simply never develops in one foot (unilaterally) or both feet (bilaterally).

Causes

Generally fallen arches are a condition inherited from one or both parents. In addition, age, obesity, and pregnancy cause our arches to collapse. Being in a job that requires long hours of standing and/or walking (e.g. teaching, retail, hospitality, building etc) contributes to this condition, especially when standing on hard surfaces like concrete floors. Last, but not least unsupportive footwear makes our feet roll in more than they should.

Symptoms

Flat feet can cause a myriad of symptoms, from experiencing pain in the foot, heels, arch, calves, the shin, the knee, the hip and into the lower back due to overworking of the hip flexors or they may find it hard to stand on tip toes.

Diagnosis

You can always give yourself the ?wet test? described above to see whether you have flat feet. Most people who do not notice their flat feet or have no pain associated with them do not think to see a foot doctor. Flat feet can lead to additional problems such as stiffness or pain, however, especially if the condition appears out of nowhere. If you think you may have flat feet, you should seek medical attention to ensure there are no additional issues to worry about. Your doctor will be able to diagnose you with a number of tests. For example, he or she may have you walk around, stand still, or stand on your tiptoes while you are being examined. Your doctor may also examine your foot?s shape and functionality. It?s important to let your foot doctor know about your medical and family history. In some cases, your doctor may order imaging tests such as x-rays or an MRI (magnetic resonance imaging) to determine a cause of your flat foot. If tarsal coalition is suspected in children, a CT scan is often ordered.

Treatment in adults generally consists of wearing spacious, comfortable shoes with good arch support. Your doctor may recommend padding for the heel (heel cup) or orthotic shoe devices, which are molded pieces of rubber, leather, metal, plastic, or other synthetic material that are inserted into a shoe. They balance the foot in a neutral position and cushion the foot from excessive pounding. For children, treatment using corrective shoes or inserts is rarely needed, as the arch usually develops normally by age 5.

Surgery is rarely needed.

Surgical Treatment

Fallen arches may occur with deformities of the foot bones. Tarsal coalition is a congenital condition in which the bones of the foot do not separate from one another during development in the womb. A child with tarsal coalition exhibits a rigid flat foot, which can be painful, notes the patient information website eOrthopod. Surgery may prove necessary to separate the bones. Other foot and ankle conditions that cause fallen arches may also require surgery if noninvasive treatments fail to alleviate pain and restore normal function.

Prevention

Flatfeet in children are often an inherited family trait, but it may be possible to prevent the condition in some cases. Recent research has shown that there are several social or cultural factors that can cause flatfeet. These factors include the following, obesity, overweight, unnecessary orthopedic treatments, wearing rigid shoes at a young age, In 1992, a study in India of 2300 children aged 4-13 demonstrated a significant difference in the rate of flatfeet among those who wore shoes regularly and those who did not. In this study, wearing inflexible, closed-toe shoes in early childhood was shown to have a negative effect on the normal development of arches. Children who were allowed to go barefoot or who wore light sandals and slippers had a much lower rate of flatfeet. In 1999, a study in Spain of 1181 children aged 4-13 revealed that the use of orthopedic shoes for treatment of flatfeet in children not only failed to correct the problem, but actually worsened the condition by preventing the normal flexing and arch development of bare or lightly protected feet. Finally, in 2006, a study of 835 children aged 3-6 showed significant differences in the rate of flatfeet based on weight, with normal-weight children having lower rates of flatfeet than children who were overweight or obese. Among adults, flatfeet due to injury, disease, or normal aging are not preventable. However, when flatfeet are related to lifestyle factors, such as physical activities, shoe selection, and weight gain, careful attention to these factors may prevent the development of flatfeet.
